  • And things like vertical bifacial solar panels can work especially amazingly on grazing land that isn’t suitable for crops.

    Counter-intuitive as they may look, they actually have a number of benefits:

    1. The panels face east and west, meaning they generate peak power in the morning and evening, which corresponds to peak demand => less need for energy storage to bridge the gap between the mid-day peak in production from traditional PV and the aforementioned morning and evening demand peaks.
    2. The panels are vertical, which makes them easier and cheaper to maintain, as dust, snow, and rain naturally shed from their surfaces.
    3. The panels get less direct energy during mid-day, keeping their surfaces cooler. Turns out cooler solar panels are more efficient at converting light energy into electrical energy.
    4. The arrangement lends itself very naturally to agrivoltaics, which means you can derive more yields from a given piece of land and use less land overall than if you had segregated uses.
    5. The compatibility with agrivoltaics allows farmers to diversify their incomes streams and/or become energy self-sufficient.

  • The raison d’être for RISC-V is domain-specific architecture. Currently, computational demands are growing exponentially (especially with AI), but Moore’s Law is ending, which means we can no longer meet our computational demands by scaling single-core speed on general-purpose CPUs. Instead, we are needing to create custom architectures for handling particular computational loads to eke out more performance. Things like NPUs, TPUs, etc.

    The trouble is designing and producing these domain-specific architectures is expensive af, especially given the closed-source nature of computer hardware at the moment. And all that time, effort, and money just to produce a niche chip used for a niche application? The economics don’t economic.

    But with an open ISA like RISC-V, it’s both possible and legal to do things like create an open-source chip design and put it on GitHub. In fact, several of those exist already. This significantly lowers the costs of designing domain-specific architectures, as you can now just fork an existing chip and make some domain-specific modifications/additions. A great example of this is PERCIVAL: Open-Source Posit RISC-V Core with Quire Capability. You could clone their repo and spin up their custom RISC-V posit chip on an FPGA today if you wanted to.

    It also had a second rule set where a land value tax was implemented, and the winning condition was when everyone made a minimum amount of money.

    A land value tax (LVT) is a levy on the value of land without regard to buildings, personal property and other improvements upon it.[1] It is also known as a location value tax, a point valuation tax, a site valuation tax, split rate tax, or a site-value rating.

    Some economists favor LVT, arguing it does not cause economic inefficiency, and helps reduce economic inequality.[2] A land value tax is a progressive tax, in that the tax burden falls on land owners, because land ownership is correlated with wealth and income.[3][4] The land value tax has been referred to as “the perfect tax” and the economic efficiency of a land value tax has been accepted since the eighteenth century.[1][5][6] Economists since Adam Smith and David Ricardo have advocated this tax because it does not hurt economic activity, and encourages development without subsidies.

    LVT is associated with Henry George, whose ideology became known as Georgism. George argued that taxing the land value is the most logical source of public revenue because the supply of land is fixed and because public infrastructure improvements would be reflected in (and thus paid for by) increased land values.[7]

    It’s just a stupidly good tax policy, and we should be implementing it in more places.

  • It’s especially dumb because RISC-V is – dare I say it – inevitably the future. Trying to crack down on RISC-V is like trying to crack down on Linux or solar photovoltaics or wind turbines. That is, you can try to crack down, but the fundamental value proposition is simply too good. All you’ll achieve in cracking down is hurting yourself while everyone else gets ahead.
